I went to the Home & Garden Show recently & think they might be what you're looking for & there details are: Calliaghstown, Rathcoole, Co. Dublin. Tel: 458 0729 or e-mail: firstname.lastname@example.org
At the show they had pieces made out of granite & other stone.
If not I have a number at home (somewhere
) of another Company in Dublin (on the outskirts
Let me know if the place in Rathcoole can get you what you need if not will root out the other number.
